10 years ago, $30k bought you a Nissan Leaf with 80 miles of range.
Fast forward to today, and the same not-inflation-adjusted amount of money buys you a Chevy Bolt with around 240 miles of range.
I expect that within the next 10 years, a vehicle with the average new MSRP will get 400-500 miles of range on a charge. Even if that prediction doesn't pan out, we can almost guarantee that typical charging speeds will increase and charging networks will expand further, blowing past critical mass.
